It's rare. To me, it's not just a synonym for "handsome", but rather implies a certain kind of elegant good looks. The male characters in JoJo's Bizarre Adventure are the first example that springs to mind.
I don't find it common for humans in general, with exception of Trump? It is kind of not not how people normally talk.
Bun this exact day I have seen similar phenomenon with "elegant". Search for elegant ended with exactly one guy and a lot of young women with dresses, most of them brides. Elegant is commonly used for good looking men.
